This is a set of dialogs written by MIT (mascript usetts Institute of Technology) to help people understand Kerberos principles. There are two fictional figures: Athena and Euripides. Through the constant conception of Athena and the constant search for vulnerabilities in Euripides, we can understand the principles of the Kerberos protocol.Athena: Athena, goddess of wisdom and skill.Euripides: the tragic po

In this article, I will discuss how to configure a Unix client based on the Network File System and use Kerberos security verification through the rpcsec_gss protocol to connect to a Windows Server under the Network File System. Traditional Network File System clients and servers use system integration to authenticate security verification. Most importantly, it allows a client to send verification information indicating the user ID or user group ID of

The Kerberos protocol was first proposed by MIT and is an identity authentication protocol. Application scenarios:In an open environment, if a Workstation user wants to request various services distributed in the network through the network, the server can only provide services to authorized users, and can identify the types of service requests. Principles of Kerberos protocol:Kerberos provides a centralize

Vi. User2User Sub-Protocol: effectively safeguards Server security Through the introduction of three Sub-protocols, we can fully master the entire Kerberos authentication process. In fact, in the Windows 2000 era, Kerberos-based Windows Authentication is implemented according to this workflow. However, as I mentioned at the end of the previous section, Kerberos b

Kerberos is an authentication system based on symmetric keys. In fact, it sometimes works better than PKI Based on asymmetric keys. Especially in small-scale network architecture, Kerberos is more centralized and convenient for management, it is even more efficient. I believe that many people can read this classic conversation, but after reading it, many people also need time to digest it. In fact, this con

Security has been a problem recently, such as Windows authentication, asymmetric encryption, digital certificates, digital signatures, TLS/SSL, and WS-Security. If time permits, I would like to write a series of articles to share and exchange with the majority of users. For many readers, Windows certification is a familiar and unfamiliar topic. Directory1.

4. Introduce Ticket Granting Service Through the above introduction, we found that Kerberos is actually based onTicket. To obtain Server resources, the Client must first pass Server Authentication. A prerequisite for authentication is that the Client provides the Server withMaster Key of the ServerEncryptedSession Ticket (Session Key + Client Info). In this case, Session Ticket is a Ticket for the Client to enter the Server field. The Ticket must be
